From version 4.7 if user has first and last name entered it should display full name, otherwise it will display username in most modules, but there are some that will still show username and there is no central point where you can change this. Can you tell us what version of MonoX you're using and where you're having problems with display name and I'll see what would be easiest way to change this. In case module is using templates, you can change template to show display name and if you're not that lucky you would need to get dirty and extend controls.

Thank you,
we are using Monox v4.5.32xx (now I am not in the office)

I look forward to your reply

Are you able to upgrade MonoX to version v4.7, in the version you're using this will be much harder to achive?

I know...but at the moment it is impossible to upgrade to the newer version

Ok,

Here is a general idea. In case of templates you can access original entity used for binding through $Container.DataItem. First you can try to replace username with $Container.DataItem.AspnetUser.UserDisplayName. There is no guarantee user profile will be fetched and in that case you need to extend webpart and replace username with your display name. You can find basic steps for extending webparts in this blog. Once you extend easiest way is to override ParseTemplateTags, find username tag used in template and replace value with your display name.

When having small active user base (around 100 users) caching will work just fine, in case of larger user base you should consider fetching profiles from database in that case you would need to override BindData to get list of user ids and fetch their user profiles from db and use this list inside ParseTemplateTags.

When you have extended webpart you must replace MonoX webpart with your own on your pages and that should be it.
